摘要:
In a data processor including a master circuit that issues an access request and slave circuits that perform processing in response to the access request received from the master circuit, the disclosed invention enables the master circuit to access all data areas of the slave circuits even if the master circuit does not have an access command in data size suitable for accessing the slave circuit. An access size control unit that can convert access size input from the master circuit to data size in which the slave circuit accepts access is installed between the master circuit and the slave circuit. The access size control unit retains at least one address for access size setting. As the master circuit accesses the appropriate address for access size setting, the access size conversion procedure can be carried out.

A data processing device which, even if congestion occurs on a bus circuit of a specific processing circuit in an LSI in which multiple circuit modules are connected by buses, can fully actualize the performance potential of the system on chip. Buses and slave circuits on which accesses concentrate are provided with observation blocks. Each observation block has a mechanism to notify system control circuits such as a clock controller and master circuits such as CPU cores of the acquired status information, and each master circuit further has a mechanism capable of dynamically altering the priority order for notifying the bus circuits and slave circuits of the priority order of processing.

An antenna device includes an antenna element and a printed circuit board on which the antenna element is mounted. The antenna element includes a base, a radiation conductor formed on an upper surface of the substrate and one end of the radiation conductor being an open end, a plurality of terminal electrodes formed on a bottom surface of the substrate, and a loop conductor of a substantially U-shape. The loop conductor is arranged to face one of the terminal electrodes via a gap having a predetermined width. An antenna mounting region is provided on a upper surface of the printed circuit board to be adjacent to an edge of a long side of the printed circuit board. A feed line is led in the antenna mounting region along the edge. One and the other end of the loop conductor are connected to the feed line and a ground pattern, respectively.

In a sensor network system comprising a sensor terminal and a management server, the sensor terminal transmits observation data acquired using the sensor, the management server has a latest data storage manager which manages the latest observation data among observation data received from the sensor terminal, a history data storage manager which manages the history of the observation data from any time when data was received from the sensor terminal to the latest observation data, and a missing data manager which manages missing history data, and compensates the missing history data based on a predetermined rule, and when a request for such observation data is received, at least one of the latest observation data managed by the latest data storage manager, and history data wherein the missing data has been compensated and managed by the history data storage manager, is output according to the type of request.

Provided is an information processing system which has a plurality of tags, a tag reader, a digital-pen, and a server. The plurality of tags each hold a tag identifier. The tag reader reads the tag identifier held in each of the plurality of tags. The digital-pen reads location information, which identifies a location where handwriting is made on paper. The server keeps work record including information that associates the tag identifier recorded in the server in advance with the location on paper. When it is judged that the read tag identifier and a handwriting location identified by the location information are associated with each other, the server judges whether or not the read tag identifier matches the tag identifier recorded in advance that is associated by the work record with the handwriting location identified by the location information. The server outputs a result of the judging.

A module with embedded semiconductor IC of the present invention includes a first resin layer, a second resin layer, post electrodes passing through the first and second resin layers, and a semiconductor IC mounted as embedded between the first resin layer and the second resin layer. Stud bumps are formed on land electrodes of the semiconductor IC and positioned with respect to the post electrodes. Owing to this positioning of the stud bumps formed on the semiconductor IC with respect to the post electrodes, the planar position of the stud bumps is substantially fixed. As a result, it is possible to use a semiconductor IC having a very narrow electrode pitch of 100 μm or smaller, particularly of around 60 μm.

A sensor node may be used for another purpose for a moment and may also be replaced. By configuring, for a sensor node, a logic node which is provided with the physical node use information indicating whether or not the sensor node is in use and the logical node use information indicating whether or not the sensor node is provided as a logic node, a sensor node to be replaced may be specified based on the replacement request of the sensor node, a sensor node is selected which is configured as logic node providing the physical node use information indicating that the sensor node is not used and the logic node use information indicating that the sensor node is provided as the logic node, thus selected sensor node is identified as the replacing sensor node to achieve the replacement from the replaced sensor node to the replacing sensor node.

A conventional problem with commodity quality control in a traceability system is inability to appropriately change settings for quality measurement according to environmental changes. The present invention provides a system which solves the problem and realizes real-time quality control with low power consumption. In the system for commodity quality control and operations management according to the present invention, an IC tag and a sensor node for quality measurement are attached to each commodity. The system has a mechanism for detecting either one or both of a change in the location of the commodity and a change in the work performed for the commodity. The sensor node for quality measurement can appropriately change settings for quality measurement according to a change in the location of the commodity or in the work performed for the commodity.
